You cannot take the square root of a negative number and get a real number answer. You can only get an imaginary root.
square root of 49 = 7 and square root of 64 = 8
square root of 61 is between 7 and 8.
It would be closer to 8.
square root of -49 = 7i and square root of -64 = 8i
square root of -61 would be closer to 8i

Answer:
49
Step-by-step explanation:
Every time you multiply both sides of a rectangle by a number x, its area if multiplied by 
.
In our example:
Area of a rectangle = width . length
width = 4
length = 7
= 4 . 7 = 28
When you multiply both sides by 7:
width = 4 . 7 = 28
length = 7 . 7 = 49
= 28 . 49
= 1372
/ = 1372 / 28 = 49 = 
Both sides multiplied by 7 => Area multiplied by 
Got it?
